CONNECTION DIAGRAM
REAR PANEL OVERVIEW
1. POWER INPUT – Connect the included
power cable to this input and connect the
other end of the cable to a power source.
Make sure the subwoofer's POWER
SWITCH is set to "off" when plugging and
unplugging the cable.
2. POWER SWITCH – Turns the subwoofer
on/off. Make sure the VOLUME knob is set
to "zero" before turning it on.
3. POWER LED – Illuminates when the
subwoofer is on.
4. VOLUME – Turn this knob to adjust the
subwoofer's volume.
5. INPUTS – Use standard XLR cables (not
included) to connect your sound source to
these inputs. The "LEFT/MONO" INPUT can
accept either 1/4" TRS or XLR connections.
(When connecting a mono sound source,
use only the "LEFT/MONO" INPUT.)
6. OUTPUTS – Use standard XLR cables (not
included) to connect the subwoofer to the
inputs of your active speakers or powered amplifier.
7. LINK OUTPUT – Use standard XLR cables (not included) to connect the subwoofer to the inputs of an
additional amplifier (optional).
8. SIGNAL LIMIT LED – Illuminates when the audio signal being sent to the subwoofer is "clipping" or
distorting. If this light illuminates frequently or steadily, reduce the volume of your sound source.
9. GROUND SWITCH – Depressing this switch grounds the subwoofer, which can reduce hum or noise.
10. PHASE SWITCH – Depressing this switch reverses the polarity of the subwoofer's output signal. In
some cases, this can help reduce any interference in the frequency overlap between the subwoofer
and main speaker.
11. BYPASS SWITCH – Depressing this switch activates the subwoofer's high-pass filter (80 Hz).
*Note: Microphones, mixer, speakers,
and cables are not included.
